BUFFALO, N.Y. – Veteran free agent cornerback Corey Graham is coming home to Buffalo after agreeing to a four-year contract with the Bills, the player's agent has announced on Twitter.

Buddy Baker congratulated Graham on the deal in a message posted on his account Wednesday. The move comes a day after the Bills opened the NFL's free agency period losing three-time Pro Bowl safety Jairus Byrd, who signed with New Orleans.

Graham is from Buffalo, and has seven years NFL experience. He spent his first five seasons with the Chicago Bears, who selected him in the fifth round of the 2007 draft. He spent the past two seasons in Baltimore, where he had 13 starts in 32 games and won a Super Bowl.

Earlier in the day, the Bills signed free-agent offensive guard Chris Williams to a four-year contract.
